The input to send to the server, and responses to wait for, are
described as nested elements.

read

declare (as a text child of this element) a string to wait for.
The element supports the timeout attribute, which overrides any
timeout specified for the task as a whole. It also has a string
attribute, which is an alternative to specifying the string as
a text element.

It is not necessary to declare a closing <read> element like for the Telnet task. The connection is not broken until the command has completed and
the input stream (output of the command) is terminated.

write

describes the text to send to the server. The echo boolean
attribute controls whether the string is echoed to the local log;
this is "true" by default
